Risk Factors of Vulvovaginal Candidiasis among Women of Reproductive Age in Xi'an: A Cross-Sectional Study

Antifungal Plant Defensins as an Alternative Tool to Combat Candidiasis

Currently, the spread of fungal infections is becoming an urgent problem. Fungi of the Candida genus are opportunistic microorganisms that cause superficial and life-threatening systemic candidiasis in immunocompromised patients. The list of antifungal drugs for the treatment of candidiasis is very limited, while the prevalence of resistant strains is growing rapidly. Therefore, the search for new antimycotics, including those exhibiting immunomodulatory properties, is of great importance. Plenty of natural compounds with antifungal activities may be extremely useful in solving this problem. This review evaluates the features of natural antimicrobial peptides, namely plant defensins as possible prototypes of new anticandidal agents. Plant defensins are important components of the innate immune system, which provides the first line of defense against pathogens. The introduction presents a brief summary regarding pathogenic Candida species, the pathogenesis of candidiasis, and the mechanisms of antimycotic resistance. Then, the structural features of plant defensins, their anticandidal activities, their mechanisms of action on yeast-like fungi, their ability to prevent adhesion and biofilm formation, and their combined action with conventional antimycotics are described. The possible mechanisms of fungal resistance to plant defensins, their cytotoxic activity, and their effectiveness in in vivo experiments are also discussed. In addition, for the first time for plant defensins, knowledge about their immunomodulatory effects is also presented.

A Vulvovaginal Yeast Infection Caused by Cryptococcus victoriae in Vietnam: A Rare Case Report

Cases of vulvovaginitis caused by Cryptococcus genus are exceedingly uncommon, with only a handful of instances having been described for this causative species. This report describes a rare case of vulvovaginitis suspected to be caused by Cryptococcus victoriae in a 58-year-old woman residing in an urban area of Hanoi city, Vietnam. The patient with a 10-year history of depression and type 2 diabetes mellitus was admitted to the hospital due to vulvar itching and vaginal discharge. Vaginal swabs confirmed the presence of a yeast infection by direct microscopic examination with 10% KOH and culture on CHROMagar Candida. The yeast was identified as C victoriae using genetic sequencing tools. The patient's treatment plan involved topical clotrimazole and a daily oral dose of 200 mg of itraconazole for 7 days. This comprehensive treatment approach resulted in the patient's full recovery. This is the first reported case of vulvovaginitis attributed to C victoriae in humans worldwide.

Loop-Mediated Isothermal Amplification (LAMP): Potential Point-of-Care Testing for Vulvovaginal Candidiasis

PURPOSE

The aim of this study is to establish a loop-mediated isothermal amplification (LAMP) method for the rapid detection of vulvovaginal candidiasis (VVC).

METHODS

We developed and validated a loop-mediated isothermal amplification (LAMP) method for detecting the most common Candida species associated with VVC, including C. albicans, N. glabratus, C. tropicalis, and C. parapsilosis. We evaluated the specificity, sensitivity, positive predictive value (PPV), negative predictive value (NPV), and Kappa value of the LAMP method to detect different Candida species, using the conventional culture method and internal transcribed spacer (ITS) sequencing as gold standards and smear Gram staining and real-time Rolymerase Chain Reaction (PCR) as controls.

RESULTS

A total of 202 cases were enrolled, of which 88 were VVC-positive and 114 were negative. Among the 88 positive patients, the fungal culture and ITS sequencing results showed that 67 cases (76.14%) were associated with C. albicans, 13 (14.77%) with N. glabratus, 5 (5.68%) with C. tropicalis, and 3 (3.41%) with other species. Regarding the overall detection rate, the LAMP method presented sensitivity, specificity, PPV, NPV, and Kappa values of 90.91%, 100%, 100%, 93.4%, and 0.919, respectively. Moreover, the LAMP had a specificity of 100% for C. albicans, N. glabratus, and C. tropicalis, with a sensitivity of 94.03%, 100%, and 80%, respectively. Moreover, the microscopy evaluation had the highest sensitivity, while the real-time PCR was less specific for C. albicans than LAMP. In addition, CHROMagar Candida was inferior to LAMP in detecting non-albicans Candida (NAC) species.

CONCLUSIONS

Based on the cost-effective, rapid, and inexpensive characteristics of LAMP, coupled with the high sensitivity and specificity of our VVC-associated Candida detection method, we provided a possibility for the point-of-care testing (POCT) of VVC, especially in developing countries and some laboratories with limited resources.

Evaluation of the Therapeutic Effect of 15 ppm Silver Nanoparticle Spray Compared to Clotrimazole 1% on Candida Vaginitis: A Randomized Controlled Clinical Trial

Objective

In vitro and in vivo researches have shown that silver nanoparticles have more antimicrobial properties with a lower concentration than antifungal agents against candida vaginitis. Therefore, this study evaluated the therapeutic effect of silver nanoparticles (Nivasha spray15ppm) compared to clotrimazole 1% vaginal cream on candida vaginitis.

Materials and methods

In this clinical trial study, 110 women with confirmed candida vaginitis randomly were divided into test (n=58) and control (n=52) groups. Silver nanoparticles spray with an applicator (Nivasha 15 ppm), and clotrimazole 1% were administered to test and control groups, respectively. Then, within ten days, post-intervention checkup and patient self-reported for treatment results were recorded in checklists and the data were analyzed statistically.

Results

The improvement rate in test group (98.0%) was 1.44 times higher than in control (67.9%). Moreover, disease symptoms after the intervention (including unusual secretions, itching and burning, redness) in test group were significantly less than in the control, but there was no significant difference in the ratio of edema in two groups (p=0.071). Furthermore, the average recovery time (days) of all symptoms in test group was lower than control (p<0.05). Finally, the rate of patients' satisfaction with the treatment process in the test group (76.9%) was more than control (46.6%) (p=0.004).

Conclusion

Nivasha spray had more effectiveness compared to the clotrimazole 1%. Therefore, it can be used as an alternative drug in the treatment of Candida vaginitis.

Limosilactobacillus reuteri 29A Cell-Free Supernatant Antibiofilm and Antagonistic Effects in Murine Model of Vulvovaginal Candidiasis

Vaginal dysbiosis advocates burgeoning of devious human vaginal pathobionts like Candida species that possess multiple virulence properties and metabolic flexibility to cause infections. Inevitably, antifungal resistance may emerge due to their innate nature (e.g., biofilm formation), which assists in their virulence as well as the formation of persister cells after dispersal. In consequence, the phenomenon of biofilm involvement in vulvovaginal candidiasis (VVC) and its recurrence is becoming paramount. Lactic acid bacteria and their derivatives have proven to be hostile to Candida species. Here, we throw more light on the potency of the derivatives, i.e., cell-free supernatant (CFS) produced by an indigenously isolated vaginal Lactobacillus strain, Limosilactobacillus reuteri 29A. In the present study, we investigated the antibiofilm and antagonistic effects of L. reuteri 29A CFS, against biofilms of Candida species and in murine model of vulvovaginal candidiasis. In our in vitro biofilm study, the CFS disrupted and inhibited preformed biofilms of C. albicans and C. glabrata. Scanning electron microscopy displayed the destruction of preformed biofilms and impediment of C. albicans morphogenesis by the CFS. Gas chromatography-mass spectrometry analysis showed multiple key compounds that may act singly or synergistically. In vivo, the CFS showed no collateral damage to uninfected mice; the integrity of infected vaginal tissues was restored by the administration of the CFS as seen from the cytological, histopathological, and electron microscopical analyses. The results of this study document the potential use of CFS as an adjuvant or prophylactic option in addressing vaginal fungal infections.

Investigation of Luliconazole-Loaded Mucoadhesive Electrospun Nanofibers for Anticandidal Activity in the Management of Vaginal Candidiasis

In this study, we fabricated and evaluated luliconazole-loaded electrospun nanofibers for anticandidal activity in the management of vaginal candidiasis. Polycaprolactone (PCL)/gelatin nanofibers were designed by the electrospinning technique, and the Box-Behnken design (BBD) was adopted for optimization to get tailored fibers. The luliconazole (LCZ) drug was mixed into different concentrations (2.5, 5, 7.5, and 10%) of tea tree oil (TT oil) and loaded into the PCL/gelatin nanofibrous mats. The effective anticandidal potential of nanofiber samples were analyzed by the disk-diffusion method. Scanning electron microscopy (SEM), Fourier transform infrared (FTIR), differential scanning calorimetry (DSC), XRD analysis, and in silico study were performed. The entrapment efficiency, swelling degree, mechanical strength, contact angle, mucoadhesion, drug release, and permeation study were assessed. The average diameter of the PCL/gelatin-optimized nanofiber was 153 nm. SEM reflected that the fabricated nanofibers were uniform and bead-free. FTIR and DSC analyzed the interaction and physical entrapment of the drug in the polymeric fibers. The entrapment efficiency of the drug-loaded nanofiber was found to be 89.2 ± 0.8%. Maximum swelling percentages at 4 h were 40.8, 18.9, and 14.0% and contact angles were 46.5°, 62.95°, and 65.78° for the blank, TT oil-loaded, and drug-loaded nanofiber, respectively, which indicated the hydrophilic nature of the fibers. The drug-loaded nanofiber had a high tensile strength with satisfactory mucoadhesive property that led to its adhesion to the vaginal mucosa with no tear. The drug-loaded nanofiber had a cumulative drug release of 67.7 ± 3.4% in 48 h, and the 12.8 ± 0.53 mm of zone of inhibition (ZOI) in 48 h illustrated an effective anticandidal activity. The TT oil-loaded nanofiber also exhibited a small ZOI of 4.3 ± 0.30 mm, indicating a synergistic effect to the antifungal activity of the drug-loaded nanofiber. LCZ-loaded nanofibers can emerge as a novel approach for vaginal drug delivery in the treatment of candida infection. Thus, this pharmaceutical investigation can help in formulating preclinical and clinical models.

Risk factors of recurrent bacterial vaginosis among women of reproductive age: A cross-sectional study

The aim of this study was to explore risk factors of recurrent bacterial vaginosis (RBV) among women of reproductive age. This cross-sectional study was carried out in real-world conditions. Women with RBV were selected, and simultaneously uncomplicated bacterial vaginosis (UBV) and those who underwent routine gynecological examination and had normal vaginal microflora were also recruited as the control. Totally, 316 participants were enrolled. Univariate analysis showed that unemployment, desserts, and wiping were related to UBV, while there was no definite relationship between education, high body mass index, smoking, sedentary lifestyle, and RBV or UBV. History of human papillomavirus infection, contraceptive methods, age at first sexual intercourse, and not cleaning vulva during sexual activity were connected with UBV, while the history of other vaginitis and number of sexual partners in the previous year were related to both RBV and UBV. Multivariate logistic regression analysis revealed that lower educational level increased the risk of suffering RBV. Interestingly, no smoking was a protective factor. Moreover, the absence of other vaginitis and an exclusive sexual partner could also weaken the risk of incurring RBV. These various adverse factors alter endocrine function and vaginal immunity, further leading to the recurrence of BV. It is necessary to take corresponding measures to avoid risk factors and to help lessening the prevalence of RBV among women of reproductive age.

Anti-Biofilm Activity of Phenyllactic Acid against Clinical Isolates of Fluconazole-Resistant Candida albicans

Commonly found colonizing the human microbiota, Candida albicans is a microorganism known for its ability to cause infections, mainly in the vulvovaginal region, and is responsible for 85% to 90% of vulvovaginal candidiasis (VVC) cases. The development of drug resistance in C. albicans isolates after long-term therapy with fluconazole is an important complication to solve and new therapeutic strategies are required to target this organism and its pathogenicity. In the present study, phenyllactic acid (PLA) an important broad-spectrum antimicrobial compound was investigated for its antifungal and antivirulence activities against clinical isolates of C. albicans. Previously characterized strains of C. albicans isolates from women with VVC and C. albicans ATCC90028 were used to evaluate the antimicrobial and time dependent killing assay activity of PLA showing a MIC 7.5 mg mL−1 and a complete reduction of viable Candida cells detected by killing kinetics after 4 h of treatment with PLA. Additionally, PLA significantly reduced the biomass and the metabolic activity of C. albicans biofilms and impaired biofilm formation also with changes in ERG11, ALS3, and HWP1 genes expression as detected by qPCR. PLA eradicated pre-formed biofilms as showed also with confocal laser scanning microscopy (CLSM) observations. Furthermore, the compound prolonged the survival rate of Galleria mellonella infected by C. albicans isolates. These results indicate that PLA is a promising candidate as novel and safe antifungal agents for the treatment of vulvovaginal candidiasis.

The bacterial communities in vagina of different Candida species-associated vulvovaginal candidiasis

The incidence of vaginal infection caused by Candida species has considerably increased over the past two decades. Candida albicans is the main cause of vulvovaginal candidiasis (VVC); however, non-albicans Candida (NAC) species, such as Candida glabrata and Candida tropicalis, are now frequently identified in VVC patients. Although the vaginal microbiome (VMB) was well studied in Candida albicans-associated VVC patients, the fungal influence on bacterial communities of NAC species-associated VVC and potential microbial interplay contributing to VVC pathology remain elusive. We characterized VMB via Candida albicans and NAC species-associated VVC patients, as Candida albicans (CA, n = 16), Candida glabrata (CG, n = 16), Candida tropicalis (CT, n = 4), and recruiting healthy (CON, n = 20) women as references of dysbiosis and eubiosis. The bacterial diversity of the vagina in the CG group significantly declined. Further, all VVC patients have a higher abundance of Lactobacillus iners, especially for the CG group. Meanwhile, the predicted functions in all VVC are toned which may be associated with a disruption in the bacterial network. In conclusion, according to the taxonomic analysis, we found that the vaginal microbiome in C. glabrata-associated VVC women is different from that of other Candida species-associated VVC women, implying a different pathogenesis.

Stimuli-Responsive in situ Spray Gel of Miconazole Nitrate for Vaginal Candidiasis

Vaginal candidiasis is a common form of infection in women caused by Candida species. Due to several drawbacks of conventional treatments, the current research is attempted to formulate and optimize a miconazole nitrate-loaded in situ spray gel for vaginal candidiasis. The stimuli-responsive (pH and thermo-responsive) polymers selected for the in situ gel were chitosan and poloxamer 407, respectively, whereas hydroxypropyl methylcellulose (HPMC) was introduced in the formulation to further improve the mucoadhesive property. The dispersion of each polymer was carried out using the cold method, whereas the optimization of the formulation was achieved using Box-Behnken statistical design considering viscosity and gelation temperature as dependent variables. Present design achieved the optimized outcome with HPMC, poloxamer and chitosan at 0.52% (w/v), 18.68% (w/v) and 0.41% (w/v), respectively. Evaluation of drug-excipients compatibility was performed using differential scanning calorimetry, Fourier transform infrared spectroscopy, and thermogravimetric analysis where the results showed the absence of any chemical interaction between the polymers and drug component. The optimized formulation showed gelation temperature at 31°C allowing in situ phase transition in a vaginal environment; pH of 4.21 is suitable for use in the vaginal cavity, and appropriate viscosity (290 cP) at storage temperature (below 30°C) would allow spraying at ease, whereas strong mucoadhesive force (22.4±0.513 g) would prevent leaking of the formulation after application. The drug release profile showed sustained release up to 24 h with a cumulative drug release of 81.72%, which is significantly better than the marketed miconazole nitrate cream. In addition, an improved antifungal activity could be correlated to the sustained release of the drug from the formulation. Finally, the safety of the formulation was established while tested on HaCaT cell lines. Based on our findings, it could be concluded that the in situ hydrogel formulation using stimuli-responsive polymers could be a viable alternative to the conventional dosage form that can help to reduce the frequency of administration with ease of application to the site of infection, thus will provide better patient compliance.

Improved treatment of vulvovaginal candidiasis with Clotrimazole plus probiotic Lacidophilin Vaginal Capsules: A prospective, real-world study

BACKGROUND

Clotrimazole has long been used to treat vulvovaginal candidiasis (VVC), yet the antibiotic resistance, adverse effects and recurrences still bring about a great challenge for the clinicians. To explore the effect of probiotic Lacidophilin Vaginal Capsules plus Clotrimazole Vaginal Tablets (500mg) in the treatment of uncomplicated VVC, a self-controlled real-world study was conducted.

METHODS

Twenty-seven women with a normal vaginal flora and 15 women with uncomplicated VVC were recruited. The patients were treated with the single dose of Clotrimazole Vaginal Tablets (500mg) supplemented with 2 Lacidophilin Vaginal Capsules for the following 7 days. The patients were prospectively examined 4 times and the time points were at m0 (the first visit), m1 (8-10 days after the first visit), m2 (30 days after the second visit) and m3 (30 days after the third visit). However, women in the healthy normal control group were examined just once at the first visit. The obtained vaginal secretions were examined by high-throughput sequencing.

RESULTS

The mean age in healthy control group and case group was 28.63 ± 5.40y and 27.67 ± 3.33y, respectively. Finally, 46.67% (7/15) of patients were cured at the second visit, 61.54% (8/13) were cured at the third visit and eventually 72.73% (8/11) were cured. A total of 81 samples were sequenced, generating 1668 operation taxonomy units among all the samples. The bacterial composition of women in the healthy control group was exceedingly abundant and dominated by Lactobacillus, especially by Lactobacillus. crispatus, and followed by Lactobacillus. iners, Lactobacillus. jensenii and Gardneralla. On the contrary, the bacterial composition of women with VVC was relatively few and dominated by Lactobacillus. iners. During the process of treatment, the bacterial abundance of VVC patients was increased gradually. At the final visit, the abundance of vaginal flora was augmented further with the dominant bacteria being Lactobacillus. crispatus, followed by Lactobacillus. iners.

CONCLUSION

Clotrimazole Vaginal Tablets plus probiotic Lacidophilin Vaginal Capsules could improve the effect in treating uncomplicated VVC. This improved effect was achieved perhaps through improving the composition of vaginal flora and restoring vaginal microecology.

The Spray-Dried Alginate/Gelatin Microparticles with Luliconazole as Mucoadhesive Drug Delivery System

Candida species are opportunistic fungi, which are primary causative agents of vulvovaginal candidiasis. The cure of candidiasis is difficult, lengthy, and associated with the fungi resistivity. Therefore, the research for novel active substances and unconventional drug delivery systems providing effective and safe treatment is still an active subject. Microparticles, as multicompartment dosage forms due to larger areas, provide short passage of drug diffusion, which might improve drug therapeutic efficiency. Sodium alginate is a natural polymer from a polysaccharide group, possessing swelling, mucoadhesive, and gelling properties. Gelatin A is a natural high-molecular-weight polypeptide obtained from porcine collagen. The purpose of this study was to prepare microparticles by the spray-drying of alginate/gelatin polyelectrolyte complex mixture, with a novel antifungal drug-luliconazole. In the next stage of research, the effect of gelatin presence on pharmaceutical properties of designed formulations was assessed. Interrelations among polymers were evaluated with thermal analysis and Fourier transform infrared spectroscopy. A valid aspect of this research was the in vitro antifungal activity estimation of designed microparticles using Candida species: C. albicans, C. krusei, and C. parapsilosis. It was shown that the gelatin addition affected the particles size, improved encapsulation efficiency and mucoadhesiveness, and prolonged the drug release. Moreover, gelatin addition to the formulations improved the antifungal effect against Candida species.

Candida albicans can foster gut dysbiosis and systemic inflammation during HIV infection

Candida albicans (C. albicans) is a ubiquitous fungal commensal component of the human microbiota, and under certain circumstances, such as during an immunocompromised state, it may initiate different types of infection. Moreover, C. albicans continuously and reciprocally interacts with the host immune system as well as with other elements of the gut microbiota, thus contributing significantly to both gut homeostasis and host immunity. People living with HIV (PLWH), including those receiving antiretroviral therapy, are characterized by a depletion of CD4 + T-cells and dysbiosis in their gut. C. albicans colonization is frequent in PLWH, causing both a high prevalence and high morbidity. Gut barrier damage and elevated levels of microbial translocation are also fairly common in this population. Herein, we take a closer look at the reciprocity among C. albicans, gut microbiota, HIV, and the host immune system, thus throwing some light on this complex interplay.

Distribution Analysis of Candida albicans according to Sex and Age in Clinical Specimen Testing for Sexually Transmitted Diseases

The prevalence of candidiasis, a contagious disease with high morbidity and mortality, has sharply increased globally over the last two decades. Candida albicans can cause serious infections in patients with weak immunity and in recipients of prolonged antibiotic treatment. Consequently, rapid and accurate identification of species can play an important role in the treatment of candidiasis. Here, we investigated the positive rate and infection trend of Candida albicans according to age, specimen type, and sex using multiplex real-time polymerase chain reactionbased testing of samples collected for the diagnosis of sexually transmitted diseases in Korea between 2018 and 2020. When the type of specimen collected was a swab, the positive rate of Candida albicans was higher among younger women, and tended to decrease with age. Analysis of swab samples revealed higher positive rates than urinalysis. The reduction trend in positive rates by age was comparable between the overall samples and urine specimens. Among male patients, the positive rate did not differ substantially across the various types of specimens collected. Previous studies have shown a higher prevalence of non-albicans Candida species than Candida albicans in clinical specimens, and exclusion of the former from our analysis may be a limitation of this study. However, our findings contribute significantly to the literature because globally, there is a paucity of epidemiological studies using molecular techniques to detect Candida albicans in sexually transmitted disease test samples.

Vulvovaginal candidiasis in Iranian women: Molecular identification and antifungal susceptibility pattern

AIM

Vulvovaginal candidiasis (VVC), is a common fungal infection that remains a global concern. The objectives of this study were molecular identification and assessment of the antifungal susceptibility profile of Candida species, causing VVC in southeast Iran.

METHODS

A cross-sectional investigation was carried out on 119 nonpregnant females suspected of VVC between February 2019 and May 2021. Yeast samples were characterized to the species level by conventional and molecular methods. All Candida isolates were examined for in vitro susceptibility profile to six conventional antifungal drugs using Clinical and Laboratory Standards Institute guidelines.

RESULTS

Out of 119 subjects, 52 (43.7%) cases were affected by VVC, out of whom 11 (21.15%) cases had recurrent vulvovaginal candidiasis (RVVC). The species distribution was as follows; Candida albicans (n = 21; 40.4%), C. glabrata (n = 11; 21.2%), C. tropicalis (n = 9; 17.3%), C. parapsilosis (n = 5; 9.7%), C. africana (n = 3; 5.7%), C. famata (n = 1; 1.9%), C. lusitaniae (n = 1; 1.9%), and C. dubliniensis (n = 1; 1.9%). The resistance rate of Candida isolates to fluconazole, itraconazole, and voriconazole were 15.38%, 11.5%, and 3.8%, respectively. Resistance to fluconazole was obtained in 46% (5/11) of RVVC cases but only in 7% (3/41) of VVC cases.

CONCLUSION

This study demonstrated that the majority of VVC cases were caused by non-albicans Candida species which also were resistant to some antifungal agents. Hence, our findings revealed the importance of conducting periodical epidemiological studies to determine changes in species distribution. Moreover, for effective management of treatment and infection, it is imperative to evaluate the susceptibility profiles of Candida species isolated from VVC patients.

Expression pattern of drug-resistance genes ERG11 and TAC1 in Candida albicans Clinical isolates

BACKGROUND

Candida albicans (C. albicans) is an opportunistic fungus and the most common cause of vulvovaginal candidiasis (VVC). In recent years, the use of antifungal drugs has led to the incidence of drug-resistant C. albicans strains. The purpose of this study is twofold: to determine the pattern of drug susceptibility and the relationship between demographic factors and the incidence of drug resistance among C. albicans isolates and to investigate the expression pattern of drug-resistance genes ERG11 and TAC1 in C. albicans isolates.

METHODS AND RESULTS

This descriptive cross-sectional study was conducted on 50 C. albicans isolates from women with VVC. Antifungal susceptibility of the isolates was tested by M27-A3/S4 broth micro dilution method following the Clinical and Laboratory Standards Institute (CLSI) guidelines. High susceptibility rates were recorded for itraconazole and voriconazole (68%), followed by ketoconazole (46%). Fluconazole had the lowest susceptibility to C. albicans with susceptibility of 36%. The change in ERG11 and TAC1 genes expression was determined by qPCR. The mean ∆Ct values of ERG11 and TAC1genes were significantly different between fluconazole-resistant and susceptible groups (p < 0.001). Interestingly, we found that 77% of fluconazole-susceptible isolates had significantly upregulated ERG11 gene (2.9-99.0 fold). In addition, the expression of TAC1 was upregulated in 44% of fluconazole-susceptible isolates (3.86-89.8 fold).

CONCLUSION

Our finding revealed that incidence of drug resistance in C. albicans is not simply controlled by genes but is a multi-factorial phenomenon, where several factors and mechanisms are involved in the process of drug resistance.

Comparative Fungicidal Activities of N-Chlorotaurine and Conventional Antiseptics against Candida spp. Isolated from Vulvovaginal Candidiasis

N-chlorotaurine (NCT), the N-chloro derivative of the amino acid taurine, is a long-lived oxidant produced by stimulated human leucocytes. NCT has antimicrobial activities which are generally enhanced in the presence of organic material. The aim of this study was to investigate fungicidal effects of NCT and conventional antiseptics against Candida isolated from vulvovaginal candidiasis (VVC). Chlorhexidine (CHX, 1.6%), octenidine dihydrochloride (OCT, 0.08%), povidone iodine (PVP-I, 8%), boric acid (8%), and NCT (0.1% (5.5 mM)) were evaluated against forty-four Candida isolates, according to European Standard methods, at 30, 60, 90, and 120 min and 24 h in the presence of skim milk as an organic material. CHX, OCT, and PVP-I showed rapid fungicidal activity against all Candida isolates with 5–6 log10 reduction of viable counts after 30 min, whereas boric acid and NCT needed 1 h against Candida albicans and 2 h against non-albicans Candida for a significant 3 log10 reduction. NCT showed fungicidal activity (defined as ≥4 log10 reduction) against C. albicans within 90 min and C. non–albicans within 24 h. Based upon all presently available data, including our results, NCT could be used as a new agent for treatment of local fungal infections such as VVC.

Antifungal Activities of Phytochemically Characterized Hydroethanolic Extracts of Sclerocarya birrea Leaves and Stem Bark against Fluconazole-Resistant Candida albicans Strains

The study evaluated the antifungal activities of the 70% ethanol extracts of Sclerocarya birrea leaves (SBL) and stem bark (SBB) against C. albicans strains and fluconazole-resistant isolates, their antifungal effects in combination with conventional antifungals as well as their effects on the biofilms of the C. albicans strains and isolates. UPLC-QTOF-MS/MS analysis was then carried out to investigate the metabolite profile of the extracts and UPLC fingerprints developed for their routine identification as part of quality control measures. The extracts exhibited considerable antifungal activity with MIC ranging from 12.21 to 97.66 μg/mL and MFC from 12.21 to 390.63 μg/mL against the C. albicans strains and isolates. The antifungal activity of the stem bark extract was higher than the leaf extract. SBL and SBB also significantly inhibited biofilm formation (IC₅₀ = 12.49 to 164.42 μg/mL) and the mature biofilms (IC₅₀ = 91.50 to 685.20 μg/mL) of the strains and isolates of the C. albicans and demonstrated potential for their use in combination therapies with currently used antifungals especially the stem bark extract with nystatin. Metabolite profiling identified the presence of polyphenolic compounds in both leaves and stem bark mostly flavonoids, their derivatives, and proanthocyanidins, which contribute in part to the bioactivity of the plant. Whereas flavonoids like quercetin, myricetin, and their derivatives were abundant in the leaves, epicatechin monomers with their condensed tannins, including procyanidin B2 and procyanidin C, were abundant in the stem bark. Fingerprints of SBL and SBB were developed and validated and could be used as qualitative tools to authenticate the plant. The outcomes of the study show the promise of the leaf and stem bark extracts of S. birrea to be studied further and developed as antifungal agents.

Role of Vaginal Mucosa, Host Immunity and Microbiota in Vulvovaginal Candidiasis

Vulvovaginal candidiasis (VVC) is a prevalent gynaecological disease characterised by vaginal wall inflammation that is caused by Candida species. VVC impacts almost three-quarters of all women throughout their reproductive years. As the vaginal mucosa is the first point of contact with microbes, vaginal epithelial cells are the first line of defence against opportunistic Candida infection by providing a physical barrier and mounting immunological responses. The mechanisms of defence against this infection are displayed through the rapid shedding of epithelial cells, the presence of pattern recognition receptors, and the release of inflammatory cytokines. The bacterial microbiota within the mucosal layer presents another form of defence mechanism within the vagina through acidic pH regulation, the release of antifungal peptides and physiological control against dysbiosis. The significant role of the microbiota in maintaining vaginal health promotes its application as one of the potential treatment modalities against VVC with the hope of alleviating the burden of VVC, especially the recurrent disease. This review discusses and summarises current progress in understanding the role of vaginal mucosa and host immunity upon infection, together with the function of vaginal microbiota in VVC.

Virulence Factors of Candida spp. and Host Immune Response Important in the Pathogenesis of Vulvovaginal Candidiasis

Vulvovaginal candidiasis (VVC) is one of the most common types of vaginal infections in women around the world and is often underestimated by both patients and doctors. Research on the pathogenesis of fungal vaginal infections over the last 20 years has resulted in a closer understanding of the virulence factors involved in Candida epithelial invasion and their mechanisms of action. Recently, attention was drawn to the enormous complexity of the interaction between yeast-like fungi and host cells, as well as the level of complexity of the host's response to infection and their impact on the course and treatment of VVC. Our work provides a broad description of already known and some new reports on Candida virulence factors (such as phenotypic switching or biofilm formation capacity) and their importance for tissue invasion in VVC. At the same time, we also focus on interactions with host cells and local innate immune mechanisms involved in the response to vaginal fungal invasion that are now considered equally important in this case. The presented review describes the most important aspects of the still unknown pathogenicity of Candida associated with vaginal infections.

The Chitosan-Based System with Scutellariae baicalensis radix Extract for the Local Treatment of Vaginal Infections

Scutellarie baicalensis radix, as a flavone-rich source, exhibits antibacterial, antifungal, antioxidant, and anti-inflammatory activity. It may be used as a therapeutic agent to treat various diseases, including vaginal infections. In this study, six binary mixtures of chitosan with stable S. baicalensis radix lyophilized extract were obtained and identified by spectral (ATR-FTIR, XRPD) and thermal (TG and DSC) methods. The changes in dissolution rates of active compounds and the significant increase in the biological properties towards metal chelating activity were observed, as well as the inhibition of hyaluronic acid degradation after mixing plant extract with chitosan. Moreover, the combination of S. baicalensis radix lyophilized extract with a carrier allowed us to obtain the binary systems with a higher antifungal activity than the pure extract, which may be effective in developing new strategies in the vaginal infections treatment, particularly vulvovaginal candidiasis.

Mixed Vaginitis in the Third Trimester of Pregnancy Is Associated With Adverse Pregnancy Outcomes: A Cross-Sectional Study

Mixed vaginitis is a complex vaginal dysbiosis that differs from single vaginitis. Vaginitis in the third trimester may lead to adverse maternal and neonatal outcomes. The clinical characteristics, microbiological characteristics, and adverse pregnancy outcomes of mixed vaginitis in late pregnancy are worth studying. Therefore, this study investigated the clinical and microbiological characteristics of vaginitis and adverse pregnancy outcomes of patients with mixed vaginitis. We studied 1,674 women in late pregnancy who attended the Tianjin Medical University General Hospital from November, 2019 to October, 2021. We administered standardized questionnaires, performed vaginal examination and sampling plus microscope examinations, and assessed follow-up pregnancy outcomes. We cultured the vaginal discharge of the patients with mixed vaginitis to isolate pathogens and performed antimicrobial susceptibility tests of the isolated pathogens. For the patients with peripartum infection, we collected a sample to isolate pathogens. Among the 1,674 women, 66 (3.9%) had mixed vaginitis. The independent risk factor for mixed vaginitis in late pregnancy was a history of vaginitis during early and middle pregnancy (OR = 5.637, 95% CI: 3.314–9.580). The signs of vaginal erythema (63.6% vs. 42.0%), yellow discharge (81.8% vs. 59.6%), and malodor (31.8% vs. 18.8%) (P <0.05) were significantly higher in patients with mixed vaginitis than in patients with single vaginitis. Bacterial isolates of the vaginal secretions of patients with mixed bacterial vaginitis were mainly the pathogens of aerobic vaginitis and bacterial vaginosis, such as Gardnerella vaginalis, Streptococcus anginosus, and Staphylococcus epidermidis. Pathogen isolation of the vaginal secretions of patients with mixed fungus and bacteria vaginitis mainly included Candida albicans, followed by S. anginosus, Enterococcus faecalis, Staphylococcus hemolyticus, Staphylococcus aureus, Streptococcus agalactiae and Staphylococcus simulans. Women with mixed vaginitis had an increased incidence and risk of peripartum infections (6.1% vs. 1.4%, P <0.05; OR = 3.985, 95% CI:1.214–13.079). Escherichia coli is the main pathogen that causes peripartum infection. Mixed vaginitis in late pregnancy is characterized by a severe and complex phenotype, complex vaginal dysbiosis, and a long course of vaginal dysbiosis. This can lead to an increased incidence and risk of peripartum infection. Therefore, more attention should be paid to patients with mixed vaginitis in the third trimester of pregnancy.

Comparing the Effects of Two Cream Formulations, Henna (Lawsonia inermis) and Clotrimazole, on Vaginal Candidiasis: A Randomized Controlled Trial

Background: Vaginal candidiasis is the most prevalent infection among reproductive-aged women. The current treatment for this disorder includes azole compounds. Objectives: The aim of this study was to compare the effects of two creams, henna (Lawsonia inermis) and clotrimazole, on vaginal candidiasis. Methods: In this trial, 80 women with vaginal candidiasis were recruited and randomly assigned into two groups to receive either henna (n = 40) or clotrimazole (n = 40) for one week. The ethanol extract of henna was prepared. Vaginal discharge was cultured, and vaginal pH, colony formation, lactobacillus formation, and vaginitis subjective symptoms were evaluated before and one, two, and four weeks after the intervention. The chi-square test, independent t-test, and Generalized Estimating Equations were were used for analyzing the data using SPSS version 22. Results: After four weeks of the intervention, almost 90% of the women in the henna group declared no burning sensation, itching, discharge, irritation, or dyspareunia, while only 45%, 5%, 37.5%, 52.5%, and 27.5% of the participants in the clotrimazole group did not have these symptoms, respectively (P < 0.001). The means (SD) of colony formation were 290.85 (47.35) and 265.12 (37.46) in the henna and clotrimazole groups, respectively, at the baseline, which reduced to zero and 25.45 (25.09) in the 4th week of the intervention (P = 0.001). Compared with the clotrimazole group, there was a significant increase in the mean of lactobacillus formation and a significant decrease in vaginal pH in the henna group (P < 0.001). Conclusions: Henna vaginal cream could significantly reduce the symptoms of vaginal candidiasis, such as burning sensation, itching, discharge, irritation, and dyspareunia. Also, it could decrease colony formation and vaginal pH and increase lactobacillus formation.

Understanding Women's Vaginal Douching Behaviors and Practices for Consideration in the Development of a Potential Future Vaginal Microbicide Douche for HIV Prevention: A Systematic Review of the Literature

Despite clinicians consistently advising against vaginal douching, 29-92% of women worldwide report douching. This review documents women's douching practices, motivations for douching, and specific associations (or absence of associations) between vaginal douche use and vaginal outcomes thought to be associated with douching. Understanding women's existing douching behaviors and vaginal health outcomes is critical for developing a safe vaginal microbicide douche that can be used as HIV pre-exposure prophylaxis (PrEP). A vaginal douche as PrEP could help prevent new HIV infections, since emerging evidence shows some women discontinue oral PrEP. We performed a systematic review of the literature using the guidelines for Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). Articles included in the analysis (N = 48) were published 2009-2019 in English and focused on women's experiences with douching. Two trained independent reviewers assessed these articles for content on vaginal douching, including racial/ethnic focus of studies, study design, sampling, women's reasons for douching, contents of douche solutions, and associations between vaginal douching and vaginal health outcomes. Several studies focused on Black women (N = 12 studies) or had no racial/ethnic focus (N = 12). Just over half of all studies (N = 24) were cross-sectional and involved a self-reported questionnaire and lab samples. Studies sampled women from health clinics where they were (N = 13) or were not (N = 14) presenting for vaginal health complaints. Women's primary motivation for douching was for "general cleanliness" (N = 13), and most douche solutions contained water (N = 12). There was little empirical agreement between vaginal douche use and most vaginal health outcomes. Future studies of PrEP vaginal douches should be well controlled and prioritize safety to ensure positive vaginal health outcomes.

Prevalence, species distribution and antifungal susceptibility of Candida albicans causing vaginal discharge among symptomatic non-pregnant women of reproductive age at a tertiary care hospital, Vietnam

Background

Vaginal candidiasis is frequent in women of reproductive age. Accurate identification Candida provides helpful information for successful therapy and epidemiology study; however, there are very limited data from the Vietnam have been reported. This study was performed to determine the prevalence, species distribution of yeast causing vaginal discharge and antifungal susceptibility patterns of Candida albicans among symptomatic non-pregnant women of reproductive age.

Methods

Vaginal discharge samples were collected from 462 women of reproductive age in Hanoi, Vietnam between Sep 2019 and Oct 2020. Vaginal swabs from these patients were examined by direct microscopic examination (10% KOH). CHROMagar™ Candida medium and Sabouraud dextrose agar supplemented with chloramphenicol (0.5 g/l) were used to isolate yeast, and species identification was performed using morphological tests and molecular tools (PCR and sequencing). Antifungal susceptibility testing was determined according to the Clinical and Laboratory Standards Institute guidelines (M27-A3 and M27-S4).

Results

The prevalence of vaginal yeast colonization in non-pregnant women was 51.3% of 462 participants. Nine different yeast species were identified. Among these isolates, C. albicans (51.37%) was the most frequent, followed by C. parapsilosis (25.88%), C. glabrata (11.37%), C. tropicalis (4.31%), C. krusei (3.92%), C. africana (1.57%), Saccharomyces cerevisiae (0.78%), C. nivariensis (1 isolates, 0.39%), and C. lusitaniae (1 isolates, 0.39%), respectively. Among C. albicans, all 46 isolates were 100% susceptible to micafungin, caspofungin, and miconazole. The susceptibility rates to amphotericine B, 5-flucytosine, fluconazole, itraconazole and voriconazole were 95.65, 91.30, 91.30, 82.61 and 86.95%, respectively.

Conclusions

The prevalence of VVC among symptomatic non-pregnant women of reproductive age in Vietnam was higher than many parts of the world. The high frequency of non-albicans Candida species, which were often more resistant to antifungal agents, was a notable feature. Resistance rates of vaginal C. albicans isolates to antifungal agents was low. Our findings suggest that continued surveillance of changes in species distribution and susceptibility to antifungals should be routinely screened and treated.

Curcumin-Loaded Micelles Dispersed in Ureasil-Polyether Materials for a Novel Sustained-Release Formulation

Vulvovaginal candidiasis (VVC) is a vulvar/vaginal infection that affects approximately 75% of women worldwide. The current treatment consists of antimicrobials with hepatotoxic properties and high drug interaction probabilities. Therefore, this study aimed to develop a new treatment to VVC based on micelles containing curcumin (CUR) dispersed in a ureasil-polyether (U-PEO) hybrid. The physical-chemical characterization was carried out in order to observe size, shape, crystallinity degree and particle dispersion in the formulation and was performed by dynamic light scattering (DLS), scanning electron microscopy (SEM), X-ray diffraction (XRD) and through in vitro release study. The results of DLS and SEM exhibited micelles with 35 nm, and encapsulation efficiency (EE) results demonstrated 100% of EE to CUR dispersed in the U-PEO, which was confirmed by the DRX. The release results showed that CUR loaded in U-PEO is 70% released after 10 days, which demonstrates the potential application of this material in different pharmaceutical forms (ovules and rings), and the possibility of multidose based on a single application, suggesting a higher rate of adherence.

The Interplay Between Sugar and Yeast Infections: Do Diabetics Have a Greater Predisposition to Develop Oral and Vulvovaginal Candidiasis?

Diabetes mellitus (DM) is one of the most common chronic diseases impacting individuals of both developing and developed nations. DM patients have a weaker immune system in comparison to healthy subjects, rendering them more prone to develop infections. Even the typical gut microflora can become pathogenic in such immunocompromised conditions. Microorganisms belonging to Candida species are capable of causing infections in DM subjects. A comprehensive review of the literature was undertaken. The PubMed database was searched using well-defined search terms. Predefined inclusion and exclusion criteria were applied to classify relevant manuscripts. The results of the review show that DM patients have an increased susceptibility to Candida sp. This paper will summarize the previously conducted research discussing the relationship between DM and candidiasis, features specific to Candida species that make it pathogenic, and compare oral and vulvovaginal candidiasis (VVC) morbidity in diabetics versus healthy subjects.

Lactobacillus rhamnosus AD3 as a Promising Alternative for Probiotic Products

Lactobacillus strains dominate the vaginal habitat and they are associated with a lower risk of genital infections. In addition, they contribute to the conservation of the vaginal microbiota by producing postbiotic agents. Previous studies have shown that their predominance involves antimicrobial activity against urogenital pathologies. In this context, probiotics may improve treatment outcomes. The aim of this study was to evaluate the probiotic properties of lactobacilli strains of vaginal origin using a multidisciplinary approach. For this purpose, safety criteria, ability to resist at low pH and bile salts, antimicrobial activity, ability to produce biofilm, capacity to produce hydrogen peroxide and more importantly, auto-aggregation, co-aggregation (with Candida spp.) and adhesion to human cells were evaluated. The strains belonged to the species of L. crispatus, L. gasseri, L. rhamnosus and L. delbruckii. Among these, a strain of L. rhamnosus named AD3 showed the best probiotic properties. As probiotics are already in use in many clinical practice and there are no major safety concerns, L. rhamnosus AD3 showed promise in becoming a prevention and complementary treatment option for urogenital diseases. Indeed, these results suggest that strain L. rhamnosus AD3 is non-pathogenic and likely to be safe for human consumption. This study revealed the great amensalistic properties of a new L. rhamnosus strain which can aim to be used as probiotic in pharmaceutical applications.

Molecular Characterization and Antifungal Susceptibility of Candida Species Isolated From Vulvovaginitis in Jahrom City, South of Iran

Background: Vulvovaginal candidiasis (VVC) is a significant health issue due to Candida spp. Although Candida albicans is considered a major causative agent of vaginal candidiasis, non-albicans species have increased during previous decades. Objectives: This research aimed at molecular identification and assessing antifungal susceptibility of VVC isolated Candida spp. Methods: A professional physician examined two hundred and ninety-five suspected females with vaginitis. The specimens were collected by sterile cotton swabs. Swabs were inoculated on Sabouraud dextrose agar plates and then incubated for 48 - 72 hours at 35°C. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect all Candida species. Broth microdilution, according to the M27-A3 and M27-S4 CLSI documents, were employed for determining the antifungal susceptibility tests of caspofungin (CAS), voriconazole (VRC), itraconazole (ITC), fluconazole (FLU), clotrimazole (CLO), ketoconazole (KTO), amphotericin B (AMB), and nystatin (NYS). Results: A total of 295 females suspected of vulvovaginal candidiasis were examined. The culture results were positive in 50.5% (149 of 295) of specimens. According to molecular identification techniques, C. albicans 133/149 (89.2%), C. glabrata 8/149 (5.4%), and C. kefyr 2/149 (1.4%) were the main species. A mixed infection of C. albicans and C. glabrata 6/149 (4 %) was detected. The geometric mean values to all Candida strains were in increasing order as the following: CAS, 0.075 µg/mL; VRC, 0.091 µg/mL; ITC, 0.15 µg/mL; AMB, 0.22 µg/mL; CLO, 0.23 µg/mL; KTO, 0.28 µg/mL; NYS, 0.88 µg/mL; FLU, 1.48 µg/mL. Further, the MIC ranges of all Candida isolates to the tested antifungal agents were in increasing order as follows: CAS: 0.031 - 0.25 µg/mL, KTO and ITC: 0.031 - 2 µg/mL, VRC: 0.031 - 4 µg/mL, CLO and AMB: 0.031 - 8 µg/mL, NYS: 0.06 - 4 µg/mL, and FLU: 0.12 - 128 µg/mL. Conclusions: We reported 1 (7.2 %) C. glabrata isolate resistance to FLU and 2 (14.3%) C. glabrata isolates susceptible-dose-dependent (SDD) to CAS. We also reported 6 (4.5%), 5 (3.8%), and 2 (1.5%) C. albicans resistance to ITC, FLU, and AMB, respectively, but 100% C. albicans susceptible to CAS and VRC.

Laboratorial Aspects of Cytolytic Vaginosis and Vulvovaginal Candidiasis as a Key for Accurate Diagnosis: A Pilot Study

OBJECTIVE

 To identify clinical, microscopic, and biochemical characteristics that differentiate cytolytic vaginosis (CV) from vulvovaginal candidiasis (VVC).

METHODS

 The present cross-sectional study analyzed the vaginal contents of 24 non-pregnant women aged 18 to 42 years who were attended at the Genital Infections Clinic at Centro de Atenção Integral à Saúde da Mulher da Universidade Estadual de Campinas (CAISM-UNICAMP). They were diagnosed either with (CV = 8, VVC = 8) or without vulvovaginitis or vaginal dysbiosis (controls). The socio-demographic, clinical, and gynecological data were obtained from a detailed patient interview. Samples of the vaginal contents were collected for analysis of vaginal pH, gram stain, and specific fungal culture. The Kruskal-Wallis and Fisher exact tests were used to compare the differences between the groups. Odds ratios were used to compare the categorical variables. The significance level was considered at p < 0.05.

RESULTS

 Both women with CV and VVC had a lumpy vaginal discharge (p = 0,002) and vaginal hyperemia (p = 0.001), compared with controls. The inflammatory process was more intense in the VVC group (p = 0.001). In the CV group, there was statistical significance for the lactobacillus amount (p = 0.006), vaginal epithelium lysis (p = 0.001), and vaginal pH (p = 0.0002).

CONCLUSION

 Cytolytic vaginosis and VVC diagnoses rarely differ on clinical characteristics but have different laboratorial findings. The present study highlights the importance of conducting an accurate investigation through laboratory tests rather than clinical criteria to avoid misdiagnosis.

Vulvovaginal candidiasis in a murine model of diabetes emphasizing the invasive ability of etiological agents

Aim: To compare the pathogenesis of vulvovaginal candidiasis by three Candida species in diabetic mice. Materials & methods: Estrogenized and diabetic mice were challenged with C. albicans, C. tropicalis and C. glabrata. Results: Diabetic animals infected with C. albicans and C. tropicalis maintained the highest fungal burden, despite of high levels of proinflammatory cytokines (IL-6 and TNF-α), respectively. For C. glabrata, the results were similar in diabetic and nondiabetic groups. Conclusion: C. tropicalis was as invasive as C. albicans, and both were more effective than C. glabrata. This ability was attributed to filamentation, which may be stimulated by glucose levels from vaginal fluid. In addition, the high burden may be attributed to the apparent immunological inefficiency of the diabetic host.

Gender differences in risk taking behaviors for Chlamydia trachomatis

Chlamydia trachomatis (CT) is a global problem. We compared the risk taking behaviors for CT infection between men and women. Adults (2299 females, 5559 males) were administered the Risk Behavior Assessment. In women, CT was associated with candidiasis, in men with gonorrhea, genital warts, and syphilis. Risk factors for both genders were trading sex for money, use of marijuana for women, and use of Ecstasy and Viagra for men. Those with CT had higher risk perception for HIV infection and were more likely to obtain HIV testing. Patient teaching and concurrent testing for HIV and CT are imperative.

Emergence of Vulvovaginal Candidiasis among Lebanese Pregnant Women: Prevalence, Risk Factors, and Species Distribution

Objective

Candida species colonize the vagina in at least 20% of women, with rates rising to 30% during pregnancy. This study aimed at determining the prevalence and risk factors of vulvovaginal candidiasis (VVC) in pregnant women at 35-37 weeks of gestation. It also aims at finding possible correlations between VVC and vaginal colonization by other agents, such as Group B Streptococcus (GBS) and bacterial vaginosis.

Methodology

Over a one-year period, high vaginal swabs were collected from pregnant women during their regular antenatal checkup in different polyclinics in Beirut and South Lebanon. Swabs were examined microscopically, cultured on Sabouraud Dextrose Agar, and Candida isolates were identified using Chromatic Candida medium and Germ Tube Test.

Results

VVC was detected in 44.8% of samples, with C. glabrata (44.4%) and C. albicans (43.4%) being the most isolated species. Approximately, half of pregnant women (57.7%) were coinfected with Candida and bacterial vaginosis, while 26% of them carried simultaneously Candida spp. and GBS. No significant correlation was found between the occurrence of VVC and demographic, clinical, medical, and reproductive health characteristics of pregnant women. In contrast, participants with previous miscarriages and those being hospitalized during the past 12 months were more susceptible to develop vaginal C. krusei infection in comparison to other Candida species (p=0.0316 and p=0.0042, respectively).

Conclusion

The prevalence of VVC in pregnant women is an increasing trend in our community. Therefore, routine medical examination and regular screening for candidiasis in the antenatal care program is highly recommended to manage the disease and its complications.
